Details

Vercel has introduced an experimental build mode for users of Hono and Express projects. This mode allows logs to be filtered by route, similar to Next.js.

The build pipeline also gets the following improvements:

  • File extensions can be omitted in relative path imports
  • Support for TypeScript path aliases
  • Improved interoperability between ESM and CommonJS

This feature can be enabled by setting VERCEL_EXPERIMENTAL_BACKENDS=1 in the environment variables.
